Abstract

Tangential near-noncritical phase matching is reported for upconversion in silver thiogallate (AgGaS2) using a dye laser as pump. A large acceptance angle for noncollinearity as desirable from a device view point is realised. Weak temperature tunability is also exploited to realise noncriticality.
